H2S abatement in geothermal plants: Evaluation of process alternatives

A recently completed literature review shows that there is a plethora of methods currently available for H2S abatement that may be adapted to geothermal installations. The work reported here is addressed to the problem of obtaining a preliminary assessment of various process options in order to identify chose that are the most modem, economically attractive, and commercially significant. A short description of each method and comments on their performance are included. A preliminary evaluation is carried out, on the basis of a set of qualitative criteria, leading to a relatively small number of qualified processes. This selection facilitates the task of rigorously searching for the optimum process(es), for given geothermal field conditions.
